If you want to get hundreds of gigabytes as quickly as possible, then remove files in the Movies Folder. It`s quite a good idea to delete those films that you`ve already watched as they take a lot of space on a hard drive of your MacBook Pro. You can use your Mac`s Finder to locate the file and delete it. However, there is another way to do it.
